powerpc/mm: Fix section mismatch warning in stop_machine_change_mapping()

Browse Source 
Fix the warning messages for stop_machine_change_mapping(), and a number
of other affected functions in its call chain.

All modified functions are under CONFIG_MEMORY_HOTPLUG, so __meminit
is okay (keeps them / does not discard them).

Boot-tested on powernv/power9/radix-mmu and pseries/power8/hash-mmu.

    $ make -j$(nproc) CONFIG_DEBUG_SECTION_MISMATCH=y vmlinux
    ...
      MODPOST vmlinux.o
    WARNING: vmlinux.o(.text+0x6b130): Section mismatch in reference from the function stop_machine_change_mapping() to the function .meminit.text:create_physical_mapping()
    The function stop_machine_change_mapping() references
    the function __meminit create_physical_mapping().
    This is often because stop_machine_change_mapping lacks a __meminit
    annotation or the annotation of create_physical_mapping is wrong.
